I wish I could find where I read this, it was just a day or two ago…
Anyway, there was a screenwriter, again I wish I could remember who it was and where I read it, who said, in summary:
“I like to figure out the beginning and then the end. Once those are in place, I work forward and backward until the two parts meet in the middle.”
I thought this was pretty awesome advice for how to go about starting to flesh out your story.
It likely won’t work for everyone, but it’s certainly a new way to look at things.
